Title: Method for minimizing interference by reductants in biological fluids
Inventor: BELLY ROBERT T
IPC: C12Q1/04
Filed: 1987-07-21
Granted: 1993-02-09
Abstract: METHOD FOR MINIMIZING INTERFERENCE BY REDUCTANTS IN BIOLOGICAL FLUIDS              Abstract A method for the determination of cells in a sample is disclosed.  The sample is typically urine and the method is useful in removing interfering reductants from the sample.  The method comprises the steps of:          1) separating the cells from the sample, 2) washing the separated cells with:    a) an iron(III) chelate solution and b) a non-ionic surfactant solution and 3) contacting the washed cells with a redox reagent so as to produce a detectable change due to the presence of the cells.

Abstract: VIDEO DISPLAY SYSTEM                 ABSTRACT OF THE DISCLOSURE         The invention uses a multiple beam cathode ray tube to write a television type raster, or frame, with the maximum data rate and writing speed reduced by a factor equal to the number of simultaneously operating beams.  To overcome excessive slope in the picture, a stepped deflection is used such that the majority of vertical deflection occurs after a particular horizontal sweep is completed and before the successive sweep be-gins.  The scanning speed is further increased by using an optical transmission filter capable of selectively transmitting separate colors emitted by the screen of the cathode ray tube wherein a portion of the filter may be set to transmit the next color in the color se-quence while the remainder of the filter is transmitting the color presently displayed.

Abstract: An   internally   screw-threaded   socket       for incorporation in an article of footwear, such as a golf shoe, is provided on its outer surface with teeth A stud for use with the socket includes a flange and an externally screw-threaded spigot which projects upwards  from the flange and can be screwed into the socket.   Teeth      on the stud, spaced outwards from the spigot,  interengage the teeth on the socket when the spigot is screwed into the socket and prevent the stud being freely unscrewed.  The teeth on the stud and socket may be ratchet-shaped so as to make it easier to screw the stud to the socket than to unscrew it from the  socket.    The  teeth  on  the  stud  are preferably frangible so that at least some of them break off when the stud is unscrewed for replacement.   The teeth may be  so  spaced  and  located  that,  irrespective  of  the relative rotational positions of the stud and socket, at least some of the teeth on the stud are free to assume their natural shape rather than being deformed by contact with the teeth on the socket.

Title: Temperature control arrangement for an extruding process
Inventor: SMITH WILLIAM J
IPC: B29C48/03
Filed: 1988-04-14
Granted: 1991-05-14
Abstract: ABSTRACT OF THE DISCLOSURE An  arrangement  for  controlling  the  process temperature in an industrial process involving an extruding operation includes a summing element which sums the differ-ence between the process temperature and a setpoint temper-ature with the rate of change of the process temperature and conveys this sum to a proportional and integral con-troller  so  that the output thereof  acts in an inverse manner with the process temperature.  This output of the controller is summed with the change of temperature rate which has been fed forward, to generate a demand signal. The demand signal is shaped and compared to a ramp waveform to generate a variable frequency pulse for controlling a heating and/or cooling device associated with the extruding device.  A change of speed rate can also be summed to form the demand signal.

Title: Method and apparatus for interfacing to a local area network
Inventor: HART JOHN H
IPC: H04L12/46
Filed: 1988-04-22
Granted: 1993-03-09
Abstract: Docket No. F-589-P           "METHOD AND APPARATUS FOR INTERFACING TO A            LOCAL AREA NETWORK"            ABSTRACT OF THE DISCLOSURE:     A controller for a bridge interconnecting local area networks  operates  in  two  modes.  In  a  first  mode  the controller receives and transmits station data frames with previously appended frame check sums.  In a second mode the controller responds to requests for information from stations by generating data frames from an associated memory.  The controller computes and appends frame check sums and then transmits the frames and check sums to the requesting station.          The controller is constructed and is effective to operate in a way which insures that all station data frames transmitted from stations to the bridge are received by the bridge without interruption or loss during all periods of operation.  The controller receives all such frames at all times,  including the time intervals during which circuitry in the controller must be off-line and reprogrammed for changing operation between the first and second modes.
Patent CA-1302532-C (CA)
Title: Anti-galloping device
Inventor: RICHARDSON ALBERT S JR
IPC: H02G7/14
Filed: 1988-04-25
Granted: 1992-06-02
Abstract: ANTI-GALLOPING DEVICE Abstract of the Disclosure A weight is installed in a vertical plane above the subject line.  Gravity pulls the weight to an initial angle of about 140 degrees from the starting plane and thereby twists the line.  The twist angle remains fixed so long as no gallop occurs.  During galloping motion of the line, the initial twist is decreased as the line approaches the peak of motion and reinduced as the line leaves the peak.  The line correspondingly rotates between zero degrees added twist and beyond about 140 degrees, the initial added twist angle.  The rotation of the line continuously changes the profile of the air foil of the line formed by ice frozen about the line, and thereby dampens air lift and galloping of the line. The weight is attached to the line by a grip and clamp which enable adjustment of the location of the center of gravity of the weight with respect to the line.
